Boat bailing apparatus

Abstract

Boat bailing apparatus for removing water from the interior of a boat comprising: a tubular housing adapted for attachment to the transom of the boat providing a passage through which fluid may pass from the interior of the boat to the exterior thereof; an annular seat near one end of the housing; and a ball closure carried within the housing for movement between a position engaging the seat, preventing fluid flow through the passage, and positions not engaging the seat, permitting fluid flow. A cage assembly may be provided within the housing to confine the ball closure for limited axial movement in the housing passage.

I claim: 
     
       1. Boat bailing apparatus for removing fluid from the interior of a boat comprising: a tubular housing adapted for attachment to the transom of a boat providing a substantially horizontal passage through which fluid may pass from the interior of said boat to the exterior thereof;   annular seat means centrally disposed near one end of said housing providing an opening through which said fluid may flow from said boat interior and into said passage for exit to said boat exterior;   ball closure means carried within said housing for limited axial movement within said passage between a position engaging said seat means, preventing said fluid flow through said opening, and positions not engaging said seat means, permitting said fluid flow;   cage means carried within said housing and in which said ball closure means is disposed for said limited axial movement, said cage means confining said ball closure means to the center of said passage so as to leave a surrounding space between said ball closure means and said housing at all times; and   a valve member carried by said housing downstream of said cage means and manually operable from the interior of said boat to close said passage regardless of the position of said ball closure means.   
     
     
       2. Boat bailing apparatus as set forth in claim 1 including seat retainer means removably attached at said one end of said housing, removal of which allows removal of said seat means and said ball means from said one end of said housing without disturbing the rest of said apparatus. 
     
     
       3. Boat bailing apparatus as set forth in claim 2 in which the end of said housing opposite said one end is provided with an external annular shoulder for abutment against the interior side of a boat transom through which a hole is provided to sealingly receive a portion of said opposite end of said housing, said opposite end of said housing also being provided with threads for threaded engagement with a nut member on the exterior side of said transom for providing said attachment of said housing to said boat transom. 
     
     
       4. Boat bailing apparatus as set forth in claim 1 in which said cage means is adapted for substantially horizontal installation within said housing said ball closure means being responsive to movement of said boat in a forward direction for disengagement from said seat means to permit fluid flow from the interior of said boat to the exterior thereof. 
     
     
       5. Boat bailing apparatus as set forth in claim 4 in which said housing is adapted for installation below the waterline of said boat when at rest, said ball closure means being responsive to fluids on the exterior of said boat for engagement with said seat means to prevent passage of fluid from the exterior of said boat into its interior. 
     
     
       6. Boat bailing apparatus as set forth in claim 1 in which said housing is adapted for attachment to said boat so that said ball closure means, cage means and valve member are all located within the interior of said boat.
